Processing flv files?

Can I process a flv file with Audition? Thanks.

Try it. no.
FLV (Flash Video) is designed as an end-of-the-line delivery format. Not only compressed, but sealed to the extent of not being able to even play it back as a single file. This to offer some protection for copyright holders; for a long while you couldn't even edit it in any video editor. The 'hacking' performed by for instance the VLC Media Player was controversial at first, but now you can play them in Adobe's own Media Player even.
To get to the sound you need to either record it as "what U hear" from the soundcard (different brands have different names for this, and quite a few doesn't have this functionality at all), or somehow convert the video to a different format that is acceptable to Audition. VLC can help you here. This will not be the same and extracting audio from the video, and re-inseriting it to the stream again as you can do with so many other formats in Audition. It means a new full round of compression, which most likely the video or the audio or both will suffer from. As said, an end-of-line format.
Adobe seems to give up the 'Sealed' concept of the format, for good and bad, so I wouldn't be surprised to see surpport for this in an update of Audition / Audition 4.

How to control framerate in f4v/flv files in a Build / Flash process?

I am quite new to Encore and would kindly ask for an advice.
I am trying to build Flash material from projects, to be played from local PC, not necessary to be used as internet stream. In the final material I just run "index.html" and it plays in my local browser, say Google Chrome. I need that the generated f4v / flv video clips to be rendered in high quality (usually 1280x720 progressive) with framerates as high as 30 fps or 60 fps. Suppose I load in Encore CS5 as asset an AVC mp4 clip rendered with 60fps. I select preset "1280x720 Widescreen High Quality". When executing "Build / Flash..." Encore produces a flv / f4v file with 25 fps. I cannot find where to control this aspect, I would like to endup with a f4v / flv clip with same framerate as the asset, in this case 60fps. Or at least 30fps. Any idea where to control this? I do not find any controls in Encore regarding this setting. Encore simply outputs 25fps flv clips, and sometime 15fps clips (I could not find out why 15fps...). Is there a way to force Encore to output flv clips with same framerate as the original asset?
Thanks in advance!

Thank you, Stan, for looking at this problem.
Yes indeed, Flash output in Encore is limited in many ways. I have done some experimenting now. It seemes I have found a nice application for Flash, but this application was not forseen by the developers of Encore, thus it is only poorly implemented. Unfortunately. Let me explain.
I produce multimedia material (video clips with film footage, still pictures & some effects) to be watched on PC with large screens or on PC & projector. Thus I need HD resolutions. At large resolution effects may sometimes not be perceived to run smoothly unless the video clips are rendered with high framerates. A trivial example would be rolling vertical credits at end of a video clip. When the clip is rendered with 25fps or lower you need to make the credits roll to run very slowly, otherwise the rolling down looks not smooth. Smoothiness gets better with material rendered at 29,97fps or 59,94 fps. I expected Encore would keep the framerate of the original asset when transcoding to Flash f4v / flv. This does not happen. I input assets (carefully observing the accepted input formats you mentioned) with high framerate, whereas Encore produced 25fps f4v files out of them. Unfortunately DVD formats have too low resolution for my intend and BR disks are not very popular where I live. I discovered that delivering material in Flash, to be played as an off-line website from local PC in the default browser - this would be a very nice solution. Unless Encore would perform better for this job. Probably it was simply not designed for this.
My first surprise was that I ended with 25fps f4v material. Trying to change this in Project Settings was not possible. Project was started in PAL and this option was now greyed out. Ok, I started a new project from the scratch as NTSC material, now at least the generated f4v files feature 29,97 fps instead of 25 fps, which would be acceptable. Unless...
The Flash transcoding machine of Encore drastically lowers bitrate for the generated f4v / flv files. I believe somewhere near 4Mbps (but may vary, I have not tested thoroughly). This can be ok for 360p material or lower resolution, or for watching video on youtube, but for HD resolution the effects look very bad and they do not run smooth at such low bitrate. I also noticed there is a problem with the Flash Player. The same generated (poor) f4v palyed in VLC or WMP looks much better than when played with Adobe Flash Player. Not to speak about difference between playing the original asset at 59,94fps with VLC versus playing the generated f4v (25fps) with Adobe Flash Player - here the difference is enormous!
It seemes I had some unrealistic expectations from Encore. I realy like the menus one can design with it, I like the possibility to build the project as Flash, but the results are quite poor. I need to look for an alternative solution.
When issuing the first post I just hoped I was doing something wrong...

How to play and stop flv files through NetStream in AIR Application

Hi,
In a folder I have 'n' number of flv file, which are DRM protected. when the user try to play those files for the first time through my AIR application, it will prompt for username and password and gets the license/voucher from the server and store it in AIR Runtime. so that from the next time onwords it won't prompt for username and password as because it already has license/voucher.
     My problem is assume there are 500 files, such that for each file the user has to enter his credentials[username and password]. which is a stupid thing. I want to avoid this process by implementing this process internally/programetically. By playing/accessing each file through netstream from the folder and setDRMAuthenticationCredentials for that file and stop the stream. Here I am able to play each file but I am failed to stop it. I mean to say I will get the license for all the flv files internally[while loading my AIR application], such that user should not be interrupted for his credentials for each file.He should play as if he is accessing/playing a non-DRM protected file. I will be very thank full if any one help me out in this.

Batch processing FLVs on Linux

Hello,
Does anyone know of an application for Linux that can batch
process video files, or better yet 'watch' a folder for video files
to process, and convert to FLV files?
I know that Sorenson's product has this capability but it
doesn't run on the Linux platform. I am hoping to upload video
files to a server, have them automatically processed to FLVs and
play them back using the Flash Media Server app.
Thank you.

I would suggest you give Flix Engine a try. It is a
transcoder that works on Linux and I believe it can do what you are
looking for. The other solution that won't work on Linux yet is
called FlipFactory by Telestream. Flip is a transcoder that will
monitor specific areas you want and automatically transcode files.
I have been nagging Telestream to death to make a Linux port of it,
and yet they haven't.
Let me know what you come up with. I couldn't get Flix to
work properly on my Gentoo Linux OS, but it may work on yours.
Good luck.

FMS not generating flv files

livemedia developed a multimedia system where users can
record voice and video using their MIC and/or WEBCAM.
We are using that FMS feature where we can listen/watch audio
and video which were supposed to be recorded at server side.
But after we confirm that recording and request the upload of
the file at the server (which means to record the resulting flv
file at the FLV server), seems that the recoridng process get lost,
since we cannot find the flv file at the especified folder. In
other words, we can not reproduce the podcast/videocast, since the
flv file is not there.
Can anybody help us?

Hi Tool55,
Sorry, FLV is no longer a supported format for import. The workaround is to transcode in Media Encoder to a supported format. After Effects and Adobe Media Encoder still support the import of FLV files. FLV file export is still available within Adobe Premiere Pro.
Here's the knowledge base document: Can't import FLV files
Thanks,

Splitting Flv file

I need to be able to split an FLV file using Java code.
I understood that ffmpeg has this ability in command line, and that JMF can use ffmpeg.
1. Is it possible in JMF? How do I do it?
2. I thought of maybe running the ffmpeg process from java instead of using the JMF. It will be much easier, but it may have bad performance and take a lot of memory. Is that correct? If I have a need for 10 asynchronous splits, will using JMF be better?
Thanks!

also, how can I get the PrintWriter file names to be dynamic instead of declaring 3 of them like I have it now? Lets say I need 5 files now, but in the future, I may need 2 files. So the "out" variable would have the out1 and out2 only.

Quicktime and flv files

I have just bought quicktime pro because research suggested it would open a flv file and convert it. Having gone through a painful process of having to redownload and reinstall various add ons it is still not working only opening the first few seconds of the file. Can anyone suggest a solution?

Quicktime X is a great little piece of software. However, Quicktime X is very finicky on which codec/file format it can decode/play.
Luckily, there are DOZENS of alternative video/media players and extensions available for the Mac. Some of them are even FREE. Some of the better FREE ones include...
PERIAN (quicktime extension)
http://www.macupdate.com/app/mac/22923/perian
QUICKTIME 7.6.6
http://support.apple.com/kb/DL923
VLC Media Player
http://www.macupdate.com/app/mac/5758/vlc-media-player
NICEPLAYER
http://www.macupdate.com/app/mac/15136/niceplayer
... And if none of those work, there is a possibility that, that video file may be corrupted.

Editing FLV files - Split / Merge

Our studio is moving to a Flash video streaming solution from
a RealVideo streaming one. We stream multiple live streams daily
and archive our streams as well and there are times when we'd like
to edit the .flv video files to cut out a section or maybe merge
two flv files. For RealVideo files, this can be done using the Real
Media editor that is built into Real Producer. Is there any
solution to accomplish this with FLV files?
I've scoured google and I've found workarounds that involved
converting the .flv file into an avi or an mpeg, editing it and
then converting it back using multiple programs and plugins to
accomplish this, but that process is too complicated for most of
the end-users in our studio and converting the format over and over
obviously causes degradation in the quality of the video. Has Adobe
created a standalone tool to split/merge flv files? If anybody has
a solution please share. Thanks!

Hey Jason,
Your best bet is to do all the editing you need prior to
encoding. Forgive me if this is a little condescending, but for our
company, the encode to .flv format is the penultimate/final stage
of production.
I can't be sure, but I believe a program such as preniere or
after effects has good integration with Flash - you could output
directly to .flv
In terms of merging two .flvs, you're right - the options are
limited. You can either redo your edit (tricky for long sequences)
and re-encode, or alternatively code something to stick the two
flvs together...very heath robinson, i know!

Starting and Stopping FMLE from command line yields corrupt .flv files

I am using FMLE to record and live stream TV content. In order to this I am remotely calling FMLEcmd in order to start and stop encoding processes. The problem that I am running in to is that the .flv files generated are corrupt. The odd thing is that if I use the exact same profile XML from the GUI, then the encoding process works just fine and results appear as intended.
Here is the way my workflow works:
I start the process by calling
FMLEcmd /p C:\lighttpd\htdocs\xml\default.xml /l C:\lighttpd\htdocs\logs\log.txt
then at the conclusion of the recording I call
FMLEcmd /s "C:\lighttpd\htdocs\files\default.flv"
When I attempt to open the files using FFmpeg I get a codec error saying that no codecs were detected. When I attempt to open the files in VLC I get a error saying that the media types are "Undf". When I attempt to open or modify the files with flvtool2 I get an end-of-file error. My guess is that my stop command is incorrect and somehow abruptly stopping the stream, but I don't know another way to stop the stream. Do I need to specify a specific stream duration in the XML and make sure to call the stop command *after* the duration has been reached? What would cause this codec corruption when the same profile works properly from the GUI?
Here is the profile I am attempting to use.

If issue of corrupt file after cmd line not in GUI mode. Are you using some automation to copy/paste output flv to someother location?
AFAIK, after placing stop command, FMLE took some time to write proper EOF in FLV. wait ~10 sec for FMLE to complete file writing process and than play in FLV PLayer.
I tried manually with steps you mentioned and it's working fine for me.I playerd file in Applian Flash PLayer. "http://www.applian.com/flvplayer/"

CC and FLV files

Hi -
Help please - I have tried a bunch pf workarounds and nothing
seems to work.....I am doing a soft skill course in captiavte. I am
importing flv files that contain avatars, video and audio. Well,
since the audio is embedded in the flv file - I am obviously having
a problem with adding cc. Any workarounds?

quote:

Nope, not really. All you can do is approximate it,
and it may be difficult to get timing right (or not).
The first issue you will face is that Captivate "grays out"
the CC button if there is no audio on the slide. The workaround for
that is to create a tiny audio file that contains an inaudible
waveform. You won't be able to hear it, but it will fool Captivate
into accepting your closed captioning.
As to the timing issues with having your closed captioning
and the FLV audio synchronized, that is going to have to be a trial
and error process. Best of luck to you!! Larry

Group working with FLV-files

Hi,
For a couple of times now, I've wanted just to create the
FLV-file and send it to my co-workers for them to process it into a
SWF-file. I haven't been able to, though. Has anyone else succeeded
in doing this. I and my collagues have our own copies of Flash and
I've started to think that it is the problem because their Flash
won't import my FLV-files even though they are the same version
(8.0). I would like to be able to do this because then there
wouldn't have to be an SWF-file between my FLV-file and their
Flash-movie and they would have more control on the FLV-video.
My expertise is animation and theirs is web-design so it is
no use me doing the SWF-movies. On the other hand I don't want to
send them the original movie-file because it is several times
bigger than the FLV-file. It isn't reasonable
Thanks

Oops. curse you fingers. Too fast for your own good.

How are you trying to send the FLV files? This shouldn't
present any
problems at all.

Autoplaying Flash with no controls, ewwww yuck.
You could try exporting your FLA project as SWF.
DW Insert Menu > Media > Shockwave. No skins or player controls.
NOTE: don't do this if your media contains loud audio or continuosly looping animations as this will irritate some site visitors and drive traffic away from your site.

Videoplayback.flv file downloaded from YouTube video via Safari will not play

Hello All,
Here is my question to you:
Has Safari been altered in such a manner as to NOT allow you to download videos direct from YouTube to your Mac without some intermediary interface?
Here are the steps I would use to download the source .flv video file from a video on YouTube to save it on my MacBook Pro:
1. Open Safari.
2. Go to http://www.youtube.com.
3. Enter name of video to view/download in the search bar and hit 'enter'.
4. Start video.
5. While video is playing:
A) Click on 'Window' in Safari's menu bar at the top of the screen.
B) Select 'Activity'.
6. A window will open showing data status of the video.
7. Locate the largest loading file size and wait until it is finished loading.
8. Double-click on that file size.
9. A small 'Downloads' window will appear showing file download status.
10. Navigate to your 'Downloads' folder and drag the file named 'videoplayback.flv to the desktop.
11. Double-click the aforementioned file to start the video in a suitable .flv player (I was using SWF & FLV Player originally).
This process no longer works. All I get is a black screen when I double-click the downloaded .flv file.
Notes:
The file size in Step 7 above would vary accordingly to the length of the video, but now every video I try to save as a .flv is approximately 1.7MB no matter how long the video is. Something isn't right here.
I had originally downloaded and used SWF & FLV Player to view my video when the above process used to work, but now it has upgraded itself to Elmedia Player and wants me to upgrade to the PRO edition to be able to download videos from YouTube.
Any insight to this will be greatly appreciated!
Thanks in advance for reading and responding to my question!
Sincerely,
- Austin C.

Thank you for your timely response and suggestion, Mr. Davis!
I did exactly as you said, made sure there was NO trace of the Elmedia player anywhere on my machine after the uninstallation procedure, but unfortunately this did not work.
When I dropped the videoplayback.flv file into the VLC player, I get this error message:
There is something deeper going on within Safari, I believe. The fact that different length videos on YouTube all yield the same 1.7MB file size when I try to download them is puzzling.
Thoughts?

How do I download a video and convert it into an flv file? In previous versions, all I had to do was pick the resolution and it was done automaticlly. I use DVDFLICK to burn my downloaded videos to DVD.

In previous versions of Firefox, I was able to easily download and convert videos into .flv files. I was then able to burn DVDs of theses downloaded videos using DVDFLICK. I'm now unable to do this using Firefox6.0.2?

Hello,
There is a process by which you can produce a BluRay encode on a red laser DVD. See link below
from Ken Stone site.

Also this can be done in Toast 10 with the BluRay plugin, somewhat easier.
Good Luck, Tom

Wait a second, Photoshop can make lattes now? Personally I prefer my coffee black, but man have I been under-utilizing this program.

Processing flv files?
